Abstract: Regions of the Amazon are subject annually to a period of flooding, where seedlings and trees are flooded for a period. The objective of this work was to evaluate the growth and development and verify morphological changes in andiroba seedlings (Carapa guianensis Aubl.) submitted to flooding. The plants were submitted to 02 experimental treatments, without submersion (T0) and with submersion (T1) of the root system and were evaluated at 60, 90 and 120 days. The quantified variables were collar diameter, height, quantification of dry mass and observations of morphological changes. There was a significant difference for diameter at 120 days and for height at 90 and 120 days, with the highest means in diameter for T1 and height for T0. For root dry mass, there was a significant difference between treatments at 120 days, with the highest average for T1. There was a significant difference for stem, leaf and total dry mass at 90 and 120 days, with the highest averages for T0 in all variables. The plants of the T1 treatment presented lenticels that underwent hypertrophy in the submerged region and above it, and the formation of adventitious roots.
